From: Steven Baltakatei Sandoval Date: Tue, 23 May 2023 01:39:57 +0000 (+0000) Subject: fix(user/bkdatev):Make compatible with Bash 3.2.57 X-Git-Tag: 0.8.2^2~7 X-Git-Url: https://zdv2.bktei.com/gitweb/BK-2020-03.git/commitdiff_plain/be603b6fc18aaa59a35f668bc5eccd18b1ce41a0 fix(user/bkdatev):Make compatible with Bash 3.2.57 - Note: In Bash 5.1, a negative length argument in a parameter substitution (i.e. the `$len` in `${myVar:$start_idx:$len}`) causes the last characters of the $myVar string to be truncated which is convenient in various applications. However, a negative length in Bash 3.2.57 (a macOS machine I happen to have) throws an error; for compatibility, I've instead added an additional arithemetical operation to calculate the positive length that corresponds to a truncation by 2 of the total string length. --- diff --git a/user/bkdatev b/user/bkdatev old mode 100755 new mode 100644 index f2f92ec..3cc96d9 --- a/user/bkdatev +++ b/user/bkdatev @@ -2,7 +2,7 @@ # Desc: Baltakatei's verbose date command # Usage: bkdatev [args] # Example: bkdatev --date="2001-09-11T09:02:59-04" -# Version: 0.3.0 +# Version: 0.3.1 # Ref/Attrib: [1] "ISO 8601".
